I used to think that to use a bibliography, one always needs to load either biblatex or natbib however in my current thesis template, neither package is loaded and yet there is a bibliography (from .bib file generated by JabRef in biblatex mode).
When I try to use the biblatex package, I get errors reffering to the way the bibliography style is set.
What is the Latex default bibliography "tool"? Also if everything's working fine, why would I want to use biblatex?
(Using TexStudio, TexLive, JabRef)
